Specification of Letters Patent.

Application filed February 18,1907. $erial No. 358,125.

To all whom it may concern:

Be it known that 1, DAVID E. HrroLrro, a citizen of the United States,residing at San lose, in the county of Santa Clara and'State ofCalifornia, have invented new and useful Improvements in ReversibleWindows, of which the following is a specification.

This invention relates to that class of windows in which supplementalstiles or shoes are pivoted to the outer edges of the stiles oithewindow sash.

The object of this invention is to provide a reversible window having aminimum number of parts of maximum simplicity and ease of constructionand assemblage.

The accompanying drawings illustrate the invention:

Figure 1 is a broken view in elevation of a window constructed inaccordance with this invention. The supplemental stile on one side ofthe window is shown in longitudinal section along the mid-lengththereof. Fig. 2 is a view of the edge of the sash with the supplementalstile upright and the sash turned aslant. Fig. 3 is a cross section ofthe stile and supplemental stile cutting axially through the pivot online 00 Fig. 1. Fig. 4 is a section on line 5%, Fig. 1. Fig. 5 is anexaggerated iragmental sectional detail view of the supplemental stiledetached.

1 is the stile oi the window sash, the same being provided with alongitudinal groove 2 in its outer edge, said groove being deepened inthe middle to form a recess 3, in which recess a pivot plate 4 issecured by screws 5. Said pivot plate may be resilient or rigid.

G designates the supplemental stile in the form of a strip or barprovided along its inner edge with an oval tongue 7 to fit in the groove2 which is concaved to conform to the tongue of the supplemental stile.Said supplemental stile is provided on its outer face with a recess 8 inwhich a strap or bar spring 9 is mounted, the same being preferablysecured by means of screws 10 and provided with a screwthreaded hole 11.

12 is a pivot bolt extending through a hole 13 in the supplemental stile6 and connecting the pivot plate 4 and the spring 9, a screwthreadedportion 14 of said bolt being screwed into the spring 9 which is in theform of a flat spring of considerable thickness at the middle to affordsufficient length for the screwthreaded hole 11 to hold the pivot 12securely. The pivot 12 is also screwthreaded at the other end 15 and isscrewed into the pivot bar or plate 4. Preferably the middle oi the boltis not screwthreaded.

The members 4 and 9 are pivot holders, one or both oi which may beresilient; said holders comprising resilient means to hold thesupplemental stile against the stile, and the rounded or oval tongue inengagement with the groove, so that when the sash is completed thesupplemental stile and the stile on each side of the sash will be fittedtogether by tongue and groove means, open space being provided at themiddle of the recess 8 as shown, to allow suflicient movement of theresilient means to permit the tongue to move out of the groove when theframe of the window-sash is turned on its pivots. I

The flat spring or member 9 is of considerable length so that its endscome near the ends of the supplemental stile, so that the tension isapplied to the supplemental stile near enough the ends thereof to holdthe supplemental stile true and to avoid springing or warping away fromthe stile. Each stile oi the window is similarly constructed andprovided with a supplemental stile.

The supplemental stile springs 9 will normally bow away from the shoesat the middle, as indicated in Fig. 5.

In practice, to assemble the window, the pivot-plate 4 will be securedin place .by screws 5, one end of the pivot-bolt 12 will be screwedthereinto', and the supplemental stile spring 9 will be secured in placeby its screws 10. The pivot-bolt 12 normally projects far enough outwardfrom the pivot-plate 4 to pass through the hole 13 in the supplementalstile and enter the screw-threaded hole 11 in the supplemental stilespring 9, while the tongue 7 of the supplemental stile is outside thegroove 2 of the stile; so that the screw may be well started into thesupplemental stile spring 9 before any tension is brought upon theresilient means to force the tongue into the groove. The operator willthen turn the supplemental stile around on the pivotbolt 12 until thetension of the resilient means is sufiicient to hold the tongue 7firmly, though removably, in groove 2 when the supplemental stile isbrought into line with the stile 1. In Fig. 1, all tension desired maybe given by turning the supplemental stile around a sufficient number oftimes on the pivot-bolt.

When the window is installed, it will be used in the way common withreversible windows.

The tension of the springs may be increased and diminished at any timeafter the sash is in the frame, by simply revolving the sash in thewindow frame 16 until the appropriate tension is secured.

To tighten or loosen one supplemental stile without tightening orloosening the other, the sash may be detached, whereupon eithersupplemental stile may be turned independently of the other to loosen ortighten the supplemental stile.

I claim:-

1. In a reversible window provided with a stile and supplemental stile,a pivoted plate and a spring, one fastened to the stile and the other tothe outside of the supplemental stile and each provided with ascrewthreaded hole, said holes being coaxial and a pivot screwthreadedat both ends and screwed into said holes.

2. In a reversible Window provided with a stile and sup plemental stile,a plate fastened to the stile, a flat spring fastened to the outside ofthe supplemental stile and being of considerable thickness at the middleand there provided with a screwthreaded hole and a pivot screwthreadedat its ends and screwed into said plate and spring.

In a reversible Window, a stile, a plate fastened to said stile andprovided with a screwthreaded hole, a supplemental stile provided with ahole, a spring on said supplemental stile provided with a scrcwthreadedhole and a pivot screwthreaded at its ends and smooth at the middleinserted through the hole in the supplemental stile and screwed intosaid plate and spring.

4. In a reversible window, the combination with a grooved stile, of aplate secured in the groove thereof, a tong-Lied supplemental stile, afiat spring outside the sup pleinental stile and a pivot screwed intothe plate and 15 spring and connecting the same pivotally together.

In testimony whereof, I have hereunto set my hand at Los AngelesCalifornia this 11th day of February 1907.
